The objective of the program was to develop a rear end structure with improved crash energy control characteristics for late-model unitized construction American-built automobiles. Baseline tests were conducted to determine the performance characteristics of conventional automobiles in rear end impacts and to provide a basis for later evaluation of the modified vehicles. Scale model dynamic tests were conducted in a parametric study of various energy management concepts. Two basic designs were investigated in a series of full-scale development tests. These development data were used to modify and finalize the selected design. An angle barrier and a vehicle-to-vehicle impact verified that the design satisfied the program objectives. Passive head restraints were also tested on modified vehicles. The report summarizes the program effort.
